Bug 479494 – libelf compatibility issue?: ctfconvert -L VERSION -g aicasm.o , segfault 11.

• Product: Gentoo/Alt
• Status: RESOLVED FIXED

[Description Yuta SATOH 2013-08-02 11:00:57 UTC]

When using libelf included in freebsd-lib, this issue does not occur.
I think better to use libelf contained in freebsd-lib instead of sys-libs/libelf...

Steps to Reproduce:

prepare)
mkdir /9.1 && cd /9.1
wget http://distfiles.gentoo.org/experimental/bsd/freebsd/stages/amd64-fbsd-9.1/stage3-amd64-freebsd-9.1.tar.bz2
tar xjpf stage3-amd64-freebsd-9.1.tar.bz2
mkdir /9.1/usr/portage /9.1/var/tmp/portage
mount -t devfs devfs /9.1/dev
mount -t nullfs /usr/portage /9.1/usr/portage
cp /etc/resolv.conf /9.1/etc
chroot /9.1 /bin/bash

export MAKEOPTS=-j10
emerge freebsd-cddl
cd /usr/src/sys/amd64/conf
echo 'makeoptions     WITH_CTF=1' >> GENERIC
config GENERIC
cd ../compile/GENERIC
make clean && make cleandepend && make depend && make -j10
<snip>
ctfconvert -L VERSION -g aicasm.o
*** [aicasm.o] Signal 11

Got Signal 11. next step.

workaround)
cd /tmp
for num in 354888 354890 354892 354894 354896
do
wget --no-check-certificate -O ${num}.patch "https://bugs.gentoo.org/attachment.cgi?id=${num}"
sleep 10
done

cd /usr/portage/sys-freebsd/freebsd-lib
patch -p1 < /tmp/354888.patch
cp freebsd-lib-9.1-r10.ebuild freebsd-lib-9.1-r11.ebuild
cp /tmp/354896.patch files/freebsd-lib-9.1-liblink.patch
ebuild freebsd-lib-9.1-r11.ebuild digest

cd /usr/portage/sys-freebsd/freebsd-cddl
patch -p1 < /tmp/354890.patch
ebuild freebsd-cddl-9.1.ebuild digest

cd /usr/portage/sys-freebsd/freebsd-usbin
patch -p1 < /tmp/354892.patch
ebuild freebsd-usbin-9.1.ebuild digest

cd /usr/portage/dev-libs/glib
patch -p1 < /tmp/354894.patch
ebuild glib-2.36.3-r1.ebuild digest

emerge -C libelf
emerge freebsd-lib && emerge freebsd-cddl

retry)
cd /usr/src/sys/amd64/compile/GENERIC
ctfconvert -L VERSION -g aicasm.o

ok. no error. check kernel compile is successful.

make clean && make cleandepend && make depend && make -j10

done.

better fix libelf / ctfconvert then I think
